Not really. AppEngine basically uses a 'request/responce' method. basically CGI http://www.w3.org/CGI/
AppEngine can't keep connections open. Its designed for HTTP requests There is the ChannelAPI, which makes persistant connections possible (using long-polling?) but doesnt sound suitable (its still HTTP). xmpp directly might be useful as a communication medium. I dont really know much about it. Perhaps you can use it without involving AppEngine. Or AppEngine could be a 'controller' or a 'mediator' so that devices can find each other.
